Is there a way to check firmware version?

I just got my bird this morning. I am following the video to update the aircraft but it does not do the update sequence and when I checked the card it had a new readme file saying that I was installing current or older version. I guess that means the one I have is up to date but i wanted to double check before I flew, any way to do that?

Just received myP3A today. Downloaded the firmware update and placed the SD card in the bird. Started it up. It make the DJI startup noise, lights are flashing but NO DDDD sound as if it were loading the update. After 1/2 hr. I shut it off took out the card and on my computer it said results, "abort" .Any help /suggesstions would be greatly appreciated.
